What syrup is added to a venti java chip frapp?

In a venti Java Chip Frappuccino, mocha syrup is a key ingredient that enhances the overall flavor profile of the drink. The Java Chip Frappuccino is designed to deliver a rich, chocolatey experience, and mocha syrup is specifically formulated to complement the coffee and chocolate components. It provides the necessary chocolatey depth and sweetness that balances the frappuccino's cold, creamy texture.

The use of mocha syrup is integral to achieving the traditional taste of a Java Chip Frappuccino, where coffee, chocolate, and ice come together to create a delicious treat.
